I like it the way it is. It gives you a broader search and greater access to info regarding your search topic. Also you never know what you might come across. Isn't it more fun that way.
They are saying that if you typing in the word "berserk" it gives you every single thing the word "berserk" is located in, whether it be a thread title or post.
Also if you already know what you're looking for, it really isn't that hard or much work to locate it with the current search function.
